What is the concept of seafloor spreading? A. New oceanic crust is formed at mid-oceanic ridges and spreads outwards B. Continents are stationary, and only the ocean floor moves C. Movement of continents due to tidal forces D. Formation of mountains due to volcanic activity Explanation: Seafloor spreading proposes that volcanic activity at mid-oceanic ridges creates new crust, pushing the older crust outwards. 2 / 202. How are the rates of plate movement determined? A. By measuring the height of mountains B. By measuring the depth of trenches C. By observing volcanic activity D. By analyzing magnetic stripes in the ocean floor Explanation: The magnetic stripes in the ocean floor provide a record of plate movement, allowing scientists to determine the rates. 3 / 203. What is a tectonic plate? A. A large island formed from volcanic activity B. A type of volcano C. A deep trench in the ocean floor D. A massive, irregularly-shaped slab of solid rock Explanation: A tectonic plate, also called a lithospheric plate, is a massive slab of solid rock that makes up the Earth’s lithosphere. 4 / 204. What was the name of the sea that separated India from Asia? A. The Atlantic Ocean B. The Indian Ocean C. The Tethys Sea D. The Pacific Ocean Explanation: The Tethys Sea separated the Indian and Eurasian plates before their collision. 5 / 205. What is the slowest moving oceanic ridge? A. The Arctic Ridge B. The Indian Ocean Ridge C. The Mid-Atlantic Ridge D. The East Pacific Rise Explanation: The Arctic Ridge has the slowest rate of plate movement compared to other ridges. 6 / 206. Where was the Indian subcontinent located about 140 million years ago? A. Near the South Pole B. 50°N latitude C. Near the equator D. 50°S latitude Explanation: The Indian subcontinent was located much further south 140 million years ago. 7 / 207. What major event occurred during India’s movement towards Asia? A. Separation of Australia from Antarctica B. Outpouring of lava and formation of the Deccan Traps C. Formation of the Atlantic Ocean D. Formation of the Mariana Trench Explanation: The Deccan Traps were formed by massive volcanic eruptions during India’s northward movement. 8 / 208. What type of plate boundary is the San Andreas Fault? A. Transform boundary B. Convergent boundary C. Divergent boundary D. Subduction zone Explanation: The San Andreas Fault is a transform boundary where plates slide horizontally past each other. 9 / 209. When did India collide with Asia? A. 40-50 million years ago B. 200 million years ago C. 10 million years ago D. 100 million years ago Explanation: The collision of India and Asia, leading to the formation of the Himalayas, occurred around 40-50 million years ago. 10 / 2010. What is the fastest moving oceanic ridge? A. The Mid Sources and related content-Atlantic Ridge B. The Indian Ocean Ridge C. The East Pacific Rise D. The Arctic Ridge Explanation: The East Pacific Rise has the fastest rate of plate movement, with rates exceeding 15 cm per year. 11 / 2011. What does the term “Pangaea” mean? A. Supercontinent B. Land of the dinosaurs C. All earth D. All water Explanation: The term “Pangaea” translates to “all earth,” referring to the supercontinent that Wegener proposed. 12 / 2012. What happens to the oceanic crust at deep trenches? A. It is destroyed B. It becomes thicker C. It remains unchanged D. It is created Explanation: The oceanic crust sinks and is consumed at deep trenches, balancing the creation of new crust at mid-oceanic ridges. 13 / 2013. What is an example of a divergent plate boundary? A. The Mid-Atlantic Ridge B. The Himalayas C. The Mariana Trench D. The San Andreas Fault Explanation: The Mid-Atlantic Ridge is a divergent boundary where the American plates are moving away from the Eurasian and African plates. 14 / 2014. What is the asthenosphere? A. A type of tectonic plate B. The solid core of the Earth C. The rigid outer layer of the Earth D. The mobile layer beneath the lithosphere Explanation: The asthenosphere is the partially molten layer beneath the lithosphere, over which the tectonic plates move. 15 / 2015. What is the driving force behind plate movement? A. Tidal forces B. Convectional currents in the mantle C. Magnetic forces D. Volcanic activity Explanation: The heat within the mantle creates convectional currents, which are the driving force behind plate movement. 16 / 2016. What is the “rim of fire”? A. The boundary between two continents B. The edge of a tectonic plate C. The area where seafloor spreading occurs D. The zone of active volcanoes around the Pacific Ocean Explanation: The “rim of fire” refers to the region around the Pacific Ocean with a high concentration of volcanic activity. 17 / 2017. What is the northern plate boundary of the Indian plate? A. The Kirthar Mountains B. The Mid-Atlantic Ridge C. The Java Trench D. The Himalayas Explanation: The Himalayas were formed by the collision of the Indian and Eurasian plates, marking the northern boundary of the Indian plate. 18 / 2018. How many major tectonic plates are there? A. Five B. Eight C. Seven D. Six Explanation: The Earth’s lithosphere is divided into seven major and some minor tectonic plates. 19 / 2019. What is a subduction zone? A. Where crust is destroyed B. Where plates slide past each other C. Where mountains are formed D. Where new crust is generated Explanation: A subduction zone is where one tectonic plate sinks beneath another, leading to the destruction of the crust. 20 / 2020. What is the approximate age of the oldest rocks in the oceanic crust? A. 3,200 million years old B. 540 million years old C. 200 million years old D. 4,600 million years old Explanation: The age of rocks in the oceanic crust does not exceed 200 million years, significantly younger than the oldest continental rocks.Please insert your information to see your ranking अपनी Ranking जानने के लिए कृपया अपनी जानकारी भरे NamePhone Number Your score isThe average score is 0% 0% Restart quiz Category: Class 11 Geography Quizzes in English
